Inside the Birdcage is the very best 1960s Maserati engineering. Its "Birdcage" nickname comes from its unique and very innovative trellis chassis construction, made of a plethora of small tubes between 10-15 mm thick.

Once welded together (all 200 of them!), they created a structure as rigid as it was light; weighing just 36 kgs and clothed in svelte wheel-hugging aluminium body.

The Birdcagewill auction with an estimate of 2.4m-2.6m.
